kab symmetry : symmetry ua qhov chaw hla ib kab ; ib daim iav duab. kev sib hloov symmetry : symmetry uas yog tig ib ncig ntawm ib qho chaw. kev txiav txim: pes tsawg zaus ib daim duab yog rotationally symmetrical hauv ib kev sib hloov nyob ib ncig ntawm ib qho chaw.

Nyob rau hauv tas li ntawd, dab tsi yog line point thiab rotational symmetry?

point symmetry , thiab kev sib hloov symmetry , los ntawm ntau lub hauv paus geometrical. Kab Symmetry . Hauv paus, a kab ntawm symmetry yog a kab uas faib ib daim duab rau hauv ob daim iav duab. Daim duab yog mapped rau nws tus kheej los ntawm kev xav hauv qhov no kab.

Tsis tas li ntawd, cov duab puas tuaj yeem muaj ob qho tib si Reflectional thiab rotational symmetry? Nws yog reflectionally symmetrical nyob ib ncig ntawm nws ntsug axis. Koj ua tau tseem khaws cia puab los ntawm rotating nws nyob ib ncig ntawm nws centroid, qhov twg peb axes sib ntsib nyob rau hauv daim duab peb sab, los ntawm 1/3 ntawm ib tug ua tiav tig. Qhov no yog kev sib hloov symmetry . Thaum lub puab tshwm tib yam li cov xav txog , txheej txheem rau tau muaj qhov sib txawv.

Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog lub ntsiab lus ntawm rotational symmetry?

Rotational symmetry yog thaum ib qho khoom tig ib ncig ntawm qhov chaw nruab nrab (tig) tus lej ntawm cov degrees thiab cov khoom tshwm tib yam. Qhov kev txiav txim ntawm symmetry yog tus naj npawb ntawm txoj haujlwm qhov khoom zoo ib yam hauv 360-degree kev sib hloov.

4 hom symmetry yog dab tsi?

Plaub yam tseem ceeb ntawm qhov symmetry no yog kev txhais lus, kev sib hloov , xav txog , thiab glide xav txog.

Dab tsi yog qhov txawv ntawm kab rau kab voltage thiab kab rau nruab nrab voltage?

Qhov voltage ntawm ob kab (piv txwv li 'L1' thiab 'L2') yog hu ua kab rau kab (los yog theem rau theem) voltage. Qhov voltage hla txhua qhov winding (piv txwv li ntawm 'L1' thiab 'N' yog hu ua kab rau nruab nrab (lossis theem voltage)

Kab kab ntu thiab Ray yog dab tsi?

Ib kab ntu muaj ob qhov kawg. Nws muaj cov ntsiab lus kawg no thiab tag nrho cov ntsiab lus ntawm kab ntawm lawv. Koj tuaj yeem ntsuas qhov ntev ntawm ib ntu, tab sis tsis yog ntawm kab. Ib txoj kab hluav taws xob yog ib feem ntawm kab uas muaj ib qho kawg thiab mus rau qhov kawg ntawm ib qho kev taw qhia xwb. Koj tsis tuaj yeem ntsuas qhov ntev ntawm lub teeb
